Difficulty: EasyKingdom Fungi: Moulds, Yeasts, and Mushrooms

In a typical mould such as *Rhizopus*, which specialized structure is responsible for producing and housing the asexual spores?

  1. SporangiumAnswer
  2. B
    Rhizoid
  3. C
    Stolon
  4. D
    Basidium

Answer

Sporangium
In *Rhizopus*, asexual reproduction occurs when upright hyphae (sporangiophores) form terminal rounded sacs called sporangia. Within these sporangia, numerous microscopic spores are produced by mitosis, which are released when the sporangium wall ruptures.

Step-by-Step Solution

1
Identify the fungal archetype described in the question.
The target organism is *Rhizopus*, a typical bread mould representing multicellular filamentous fungi.
Different fungal groups possess distinct spore-bearing organs depending on their classification.
2
Recall the structural components of *Rhizopus* and their respective functions.
Rhizoids anchor and absorb nutrients; stolons spread horizontally; sporangiophores grow vertically and bear sporangia containing asexual spores.
Connecting fungal anatomy to specific vegetative vs. reproductive roles allows clear differentiation of structures.
